ibatis sql_Map中出现异常：Cause: java.lang.RuntimeException: JavaBeansDataExchange could not instantiate..

sql_map 原始配置

    <select id="getContacts" parameterClass="java.util.Map" resultClass="java.util.Map">

       SELECT * FROM contact t
       LEFT JOIN country c ON t.contact_id = c.country_id
       <include refid="dynamicWhere"/>

    </select>

执行后出现:

解决办法:  将配置改成如下：

   <select id="getContacts" parameterClass="java.util.Map" resultClass="java.util.HashMap">      

       SELECT * FROM contact t
       LEFT JOIN country c ON t.contact_id = c.country_id
       <include refid="dynamicWhere"/>

    </select>
